Table content overflows on sidebar

I’ve recently switched from inove to twentyseventeen (child theme), and I have problems with lower resolution (desktop) device (or resized windows) when I use some tables, as the text of the table will overlay text on the sidebar.

I’ve tried to change CSS code with:
table {
overflow-x: auto;
}

but it does not seem to have any effects.
